If going electric, then go with a corded one...WAY more power. Otherwise, get gas powered and spend the money on a good brand. I like Dolmar.

Just spend the money and get a gas model. Stihl is top choice for a lot. You could also get an Echo or Red Max for a decent price. Dolmar's great as well. As much as people want to push it, there is just no comparison in our industry. The last thing you want is a dead battery and no where to charge it.

The best of the bunch is the Oregon...for now. I demo'd a Core prototype 20" battery saw at GIE and it was serious! The Stihl is more money and doesn't get as good a review as the Oregon. They have a place for homeowners to nip and trim, pro guys keep on gassing up!

Don't get electric. Go for Stihl. (Even if you do go electric) There's a reason professional loggers use it on a daily basis. If your just doing a little chainsaw work the MS290 Farmboss is a great starter. Works for 95% of residential stuff. I just can't get it out of my mind of being tangled up in a cord while wielding a chainsaw. I always move branches out from under me before continuing for safety reasons.
